AC Power Recovery Delay| Sets the time delay for the system to power up after AC power is restored to

the system. This option is set to Immediate by default. When this option is set to Immediate , there is no delay for power up. When this option is set to Random , the system creates a random delay for power up. When this option is set to User Defined , the system delay time is manually to power up.

User Defined Delay (60 s to 600 s)| Sets the User Defined Delay option when the User Defined option for AC Power Recovery Delay is selected. The actual AC recovery time needs to add iDRAC root of trust time (around 50 seconds).
UEFI Variable Access| Provides varying degrees of securing UEFI variables. When set to Standard (the default), UEFI variables are accessible in the operating system per the UEFI specification. When set to Controlled , selected UEFI variables are protected in the environment and new UEFI boot entries are forced to be at the end of the current boot order.
In-Band Manageability Interface| When set to Disabled , this setting hides the Management Engine’s (ME), HECI devices, and the system’s IPMI devices from the operating system. This prevents the operating system from changing the ME power capping settings, and blocks access to all in-

band management tools. All management should be managed through out-of-band. This option is set to Enabled by default.

Table 20. System Security details (continued)

updates require IPMI interface to be operational. This setting needs to be set to Enabled to avoid updating errors.
SMM Security Migration| Enables or disables the UEFI SMM security migration protections. It is enabled for Windows 2022 support.
Secure Boot| Enables Secure Boot, where the BIOS authenticates each pre- boot image by using the certificates in the Secure Boot Policy. Secure Boot is set to Disabled by default.
Secure Boot Policy| When Secure Boot policy is set to Standard , the BIOS uses the system manufacturer’s key and certificates to authenticate pre- boot images. When Secure Boot policy is set to Custom , the BIOS uses the user-defined key and certificates. Secure Boot policy is set to Standard by default.
Secure Boot Mode| Configures how the BIOS uses the Secure Boot Policy Objects (PK, KEK, db, dbx).

If the current mode is set to Deployed Mode , the available options are User Mode and Deployed Mode. If the current mode is set to User Mode , the available options are User Mode , Audit Mode , and Deployed Mode.

Table 21. Secure Boot Mode

Secure Boot Policy Summary| Specifies the list of certificates and hashes that secure boot uses to authenticate images.
Secure Boot Custom Policy Settings| Configures the Secure Boot Custom Policy. To enable this option, set the Secure Boot Policy to Custom option.
Options| Descriptions
---|---
User Mode| In User Mode , PK must be installed, and BIOS performs signature verification on programmatic attempts to update policy objects.

The BIOS allows unauthenticated programmatic transitions between modes.

Audit mode| In Audit Mode , PK is not present. BIOS does not authenticate programmatic update to the policy objects and transitions between modes. The BIOS performs a signature verification on pre-boot images and logs the results in the image Execution Information Table, but executes the images whether they pass or fail verification.

Audit Mode is useful for programmatic determination of a working set of policy objects.

Deployed Mode| Deployed Mode is the most secure mode. In Deployed Mode , PK must be installed and the BIOS performs signature verification on programmatic attempts to update policy objects.

Deployed Mode restricts the programmatic mode transitions.

Creating a system and setup password

Prerequisites
Ensure that the password jumper is enabled. The password jumper enables or disables the system password and setup password features. For more information, see the System board jumper settings section.

NOTE: If the password jumper setting is disabled, the existing system password and setup password are deleted and you need not provide the system password to boot the system.

Steps

1. To enter System Setup, press F2 immediately after turning on or rebooting your system.
2. On the System Setup Main Menu screen, click System BIOS > System Security.
3. On the System Security screen, verify that Password Status is set to Unlock.
4. In the System Password field, type your system password, and press Enter or Tab. Use the following guidelines to assign the system password:
   • A password can have up to 32 characters. A message prompts you to reenter the system password.
5. Reenter the system password, and click OK.
6. In the Setup Password field, type your setup password and press Enter or Tab.  a message prompts you to reenter the setup password.
7. Reenter the setup password, and click OK.
8. Press Esc to return to the System BIOS screen. Press Esc again. A message prompts you to save the changes.

NOTE: Password protection does not take effect until the system reboots.

Using your systemsystem password to secure your system

About this task
If you have assigned a setup password, the system accepts your setup password as an alternate system password.

Steps

1. Turn on or reboot your system.
2. Type the system password and press Enter.

Next steps
When Password Status is set to Locked, type the system password and press Enter when prompted at reboot.

NOTE: If an incorrect system password is typed, the system displays a message and prompts you to reenter your password. You have three attempts to type the correct password. After the third unsuccessful attempt, the system displays an error message that the system has stopped functioning and must be turned off. Even after you turn off and restart the system, the error message is displayed until the correct password is entered.

Deleting or changing system and setup password

Prerequisites

NOTE: You cannot delete or change an existing system or set up a password if the Password Status is set to Lock.

Steps

1. To enter System Setup, press F2 immediately after turning on or restarting your system.
2. On the System Setup Main Menu screen, click System BIOS > System Security.
3. On the System Security screen, ensure that Password Status is set to Unlock.
4. In the System Password field, alter or delete the existing system password, and then press Enter or Tab.
5. In the Setup Password field, alter or delete the existing setup password, and then press Enter or Tab. If you change the system and set up a password, a message prompts you to reenter the new password. If you delete the system and set up a password, a message prompts you to confirm the deletion.
6. Press Esc to return to the System BIOS screen. Press Esc again, and a message prompts you to save the changes.
7. Select Setup Password, change or delete the existing setup password, and press Enter or Tab.

NOTE: If you change the system password or setup password, a message prompts you to reenter the new password. If you delete the system password or setup password, a message prompts you to confirm the deletion.

Operating with setup password enabled

If Setup Password is set to Enabled, type the correct setup password before modifying the system setup options. If you do not type the correct password in three attempts, the system displays the following message: Even after you power off and restart the system, the error message is displayed until the correct password is typed. The following options are exceptions:

• If System Password is not set to Enabled and is not locked through the Password Status option, you can assign a system password. For more information, see the System Security Settings screen section.
• You cannot disable or change an existing system password.
  NOTE: You can use the password status option with the setup password option to protect the system password from unauthorized changes.
